Multi Band Hysteresis Modulation Based Current Control Technique for Seven Level Grid Connected Voltage Source Inverter
This paper deals with the multiband hysteresis control technique which tracks the desired reference current and provide desired voltage and current waveform with less distortion for grid connected systems. Cascaded H bridge multilevel inverter is used in high power and medium power applications. Multiband tracks the desired reference current and is used for evaluating the performance of multile...

متن کاملLow Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage
In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
متن کاملPredictive Current Control of an Induction Machine Fed by a Two-Level Voltage Source Inverter
The main aim of this project is to design and simulate a Predictive Current Control of an Induction Machine fed by a twolevel Voltage Source Inverter using MATLAB/Simulink. A predictive current technique is used where a voltage vector with different switching states is used and the value which provides a reduced quality function is selected. The current error in the next sampling time is found ...
متن کاملVoltage Equalization of DC Link capacitors in a CHB-Based PET under the Unbalance Voltage Conditions
The unbalance currents injection by power electronic transformers in order to improve the unbalance voltage conditions of the network causes an imbalanced voltage in the DC link capacitors and creates an active powers inequality in the different phases. In this paper, the proposed control structure independently controls the active power of each phase by modifying the power angle between the vo...
